This is very infrequent so I can’t say for sure when it happens, but sometimes I see overlapped text in the area between the progress bar and the multi-choice answers. See “Listen to the audio…” in the image below.
Forgot to mention that I’m on Android 11 on a Pixel 2. (Unable to edit my own post.)
And thank you for the detailed report. I’ve checked the phrase and found that the issue happens when the translation can’t fit the screen and goes on two lines. This is now fixed and tested. Should work ok for you.
